LUBRICATOR.

EPECfIl-ICATION forming part of Lettere Patent No. 356,800, datecl February 1, 1857.

Application filed March 12, 1886.

To all whom it may concern:

Be it known that- I, GEORGE A. STANNARD, u citizen of the United States of America, residing et Chicago, in the county of (look and State of Illinois, have iuvented certain new und useful Iiuproveineuts in Lnbricutors, of which the following is o specification, reference being hud iherein to the uccompenying drowings. 4

This inveution relotes to lubricutors more particularly intended for the journal-boxes of dyuiam os and other high-speed muchinery; and it hus been my main object to provide such a lubricotor that eau be adjusted for a uniform feed end at the some time may be operated intermitteutly,liheanoil-puznp,withoutdisturbing the feed-adjustment.

For that purpose my iuvention consists of the novel devices und combinotions of devices hereinufter described and specifically cloimed.

In the uceompauyiug druwings, vFigure l represents un elevotion, und Fig. 2 a vertical section, through the center of the lubricotor; Figs. 3 und i, sections of the screw-plug and vent for filliug the luhricutor, :ind Fig. 5 a seotion online in Fig. 2.

Correspouding letters in the several figures of the drowiugsdesignste like ports.

A denotes the huse-disk, and B the copdisk, both having ri m-flanges 'for holding between the gloss tube O, these ports being secured together Toy two screws, a, passed through holes in disk B :ind topped into hosses b of disk A. Ar central nippleshoped project-ion, c, formed to the bottom of dish A, is hored for the velverod, :ind around such nipple is u nutsheped project-ion, cl, forming a screw-socket for coupling the ucckextension D, that has u serewthreaded nipple, o, to its bottom for connecting it 'to thccop of a journal-box. The cylindricol shell of this extension D hus two diametricully-opposite openingsj, and surrounds o glass tube, E, the ends of which ure packed :ind elamped between the bottom of disk A :ind a. bottom shoulder in such extension D. A central nipple-shuped projeetion, g, is also formed to the top of cap-disk B, and is bored for the volvo-rod F. This rod F has to its bottom end o, oonicelly-pointed head, fz, which is the volvo proper, and shouldcrs against the Serial No, 195,008. (No model.)

end of nipple c, tliet when closed it will form a hermetic joint therewith. From above this Vulve to point i, which is about u quorter of an inch above buscA, the rod F is formed triangulur to provide oil chennels, and just below disk B the rod l? is serew-threaded, :ind is tupped through u cross-hur, G, the ends of which are hored and passed over the shunks of screws ce, to be guided ther-con. A spiral spring, j, surrounds the volvo-rod F between the base A and cross-bar G, yie-ldiugly pressing such cross-barugainst dish B. The upper part of Volvo-rod F is passed through disk B, and hos seeured upon its upper extremity by a, knob-shuped nut, m, u T-hondle, vi, by which the vulverod can be rotated, und the opening of the va-lve h can be adjusted to feed c uniform supply of oil t-o the journal, :ind in case e journal becomes hot from frietionon account of un insufficient supply of the lubrieant the ottendant by pressing upon knob m once or mere each strolze of the volvo-rod will force os much oil to the journal os is contained in the ehannels formed hy the triongulur portion of such valverod, und by releasing the pressure efter each strolre the spring j will lift the volvo again to the position it hed been adjusted to 'for u uniform feed. The amount of feed of the lubricant through valve hcuu be inspected through openings fond gloss tube E.

The opening for filling the lubricetor with oil consists of a, serew-th'resdcd socket, o, in cup-disk B, and of a. cylindricul core, p, in the center of such socket, thus leaving en unnular groove through the bottom of which are drilled four (more or less) holes, s, leading into the lubricator. The screw-plug R, fitting the screwthread in the onnulur groove, is bored out conicall from about the middle toward each end, its middle or smallest diameter portion forming e close joint with the core p when screwed down, as shown by Fig. 8. XVithout entirely removing this plug It, and by unscrewing it only e few turns, the oil poured into the funnel-shuped mouth of plugl Rwill flow into the aunulur groove and thencc through holes s into the luhricator. X-Vith this device the ottendant not only saves the time of unscrewing entirely, and then replucing egein the plug that cannot he misplaced, os when disconuected, hut

IOO

at the same time this plug` furnishes a convenient funnelifor filling the lubricator.

I am aware that a lubricator has been used wherein a valve or plunger rod hus been operated upon by a separate and distinet rod or plunger, and therefore I diselaim such a construction.

What I claim is- 1. In a lubrieator consisting of plates A and B and glss casing O, the combination, With such parts, of a plunger-rod, F, extending through plate B and provided upon its upperend with knob m, and.T-=hand1e n, valve h, secured upon the lower end of rod F, and springjgvound GEORGE A. STANNARD.
